The datasets that are already annotated and should be used for training. If you only use one dataset please use list of one.
adata_trains = [sc.read(pkg_resources.resource_filename('besca', 'datasets/data/Smillie2019_processed.h5ad'))]
The dataset of interest that should be annotated.
adata_pred = bc.datasets.Martin2019_processed()
adata_orig = bc.datasets.Martin2019_processed()
Give your analysis a name.
analysis_name = 'auto_annot_Martin2019_with_Smillie2019_dblabel'
Specify column name of celltype annotation you want to train on.
celltype_train ='dblabel'
celltype_test = 'dblabel'
Choose a method:
method = 'logistic_regression'
Specify merge method if using multiple training datasets. Needs to be either scanorama or naive.
merge = 'scanorama'
Decide if you want to use the raw format or highly variable genes. Raw increases computational time and does not necessarily improve predictions.
use_raw = False
You can choose to only consider a subset of genes from a signature set.
genes_to_use = 'all'
This function merges training datasets, removes unwanted genes, and if scanorama is used corrects for datasets.
adata_train, adata_pred = bc.tl.auto_annot.merge_data(adata_trains, adata_pred, genes_to_use = genes_to_use, merge = merge)
merging with scanorama using scanorama rn Found 1054 genes among all datasets [[0. 0.55297257] [0. 0. ]] Processing datasets (0, 1) integrating training set calculating intersection
The returned scaler is fitted on the training dataset (to zero mean and scaled to unit variance).
classifier, scaler = bc.tl.auto_annot.fit(adata_train, method, celltype_train)
[Parallel(n_jobs=10)]: Using backend LokyBackend with 10 concurrent workers. [Parallel(n_jobs=10)]: Done 5 out of 5 | elapsed: 27.4min finished
Use fitted model to predict celltypes in adata_pred. Prediction will be added in a new column called 'auto_annot'. Paths are needed as adata_pred will revert to its original state (all genes, no additional corrections). The threshold should be set to 0 or left out for SVM. For logisitic regression the threshold can be set.
adata_predicted = bc.tl.auto_annot.adata_predict(classifier = classifier, scaler = scaler, adata_pred = adata_pred, adata_orig = adata_orig, threshold = 0)
